 he georeferencer results give me a broken or not-well georeferenced image.
 I tried more than one georef-mode, helmert tsp, linear ... both gived me a
 wrong results (the pdf report font/layout size, is ok).

 I tried to georeference a an already georeferenced image (gtiff). seems
 the problem is in "srcY" that has a negative sign, see :
